the class ConstructorResolver method instantiateUsingFactoryMethod.

/**
 * Instantiate the bean using a named factory method. The method may be static, if the
 * bean definition parameter specifies a class, rather than a "factory-bean", or
 * an instance variable on a factory object itself configured using Dependency Injection.
 * <p>Implementation requires iterating over the static or instance methods with the
 * name specified in the RootBeanDefinition (the method may be overloaded) and trying
 * to match with the parameters. We don't have the types attached to constructor args,
 * so trial and error is the only way to go here. The explicitArgs array may contain
 * argument values passed in programmatically via the corresponding getBean method.
 * @param beanName the name of the bean
 * @param mbd the merged bean definition for the bean
 * @param explicitArgs argument values passed in programmatically via the getBean
 * method, or {@code null} if none (-> use constructor argument values from bean definition)
 * @return a BeanWrapper for the new instance
